Average
Description Displays the mean value of current waveform between Cursors 0 and 1.
  The currently selected waveforms vector is integrated between cursor 0 and 1 and the result is divided by the interval between cursors to obtain the average value. The result is reported in the accumulator.

Example

Open scope and paste this script into the command window.
Then press <Ctrl + R> to plot a sine wave.

Press <a> to see the average value; notice that accuracy improves as numpoints is increased.

 Parametric Cursor
Description Makes the current trace a master trace and creates a linked parametric plot and trace with auto-labels linked to the master trace and cursor 1. This makes it possible to analyze curve families, such as those created by a DC sweep.
  The currently selected waveforms vector is integrated between cursor 0 and 1 and the result is divided by the interval between cursors to obtain the average value. The result is reported in the accumulator.
